Active object oriented database management systems (AODBMS) are finding increasing application in different application domains and especially for cooperative and long duration activity management. In this paper, we propose a concurrency control mechanism for open nested transactions in an AODBMS. It exploits the semantics of the transactions to achieve(More)
Active database management systems(ADBMS) uses Event-Condition-Action rules (ECA rules). Each ECA rule speciies what action to be taken when an event occurs and the speciied condition is satissed. In this paper, we introduce a concurrency control scheme for handling nested cooperative transactions using detached mode ECA rules of an ADBMS. A state(More)
Active database management systems (ADBMS) are used in different application domains and especially for cooperative and long duration activity management. This paper deals with performance analysis of long-lived cooperative transaction processing in an ADBMS. We first briefly discuss NP-QuadLock – a concurrency control scheme for cooperative and long(More)
